Majority of these consumers who dwell in cities therefore demand leafy vegetables for their daily consumption. The demand has created the opportunity for many urban dwellers to join the business of vegetable cultivation using every space available. Urbanization is associated with industrialization, and with it comes the attendant anthropogenic hazards. Sub...

A Review of Environmental Contamination by Organochlorine and Organophosphorus Pesticides in Egypt
Farag M Malhat, Naglaa M Loutfy, Sara M Greish and Mohamed Tawfic Ahmed
Article Type: Review Article | First Published: November 26, 2018
All pesticides are potentially toxic to all sorts of life and some are even classified as probable human carcinogens, neutrotoxics and endocrine system disruptors. The toxicity level of a pesticide depends on the lethal dose (LD) of the chemical, the length of exposure, and the route of entry or absorption by the body. There are many different pesticides in use today with very different modes of action and levels of toxicity. To protect the public, WHO has developed a hazard classification syste...

In the current paper, the Localized Surface Plasmon Resonance (LSPR) effect induced by Cadmium Oxide (CdO) nanoparticles is used to observe Raman spectrum of human cancer cells, tissues and tumors. The diagnosis and treatment of human cancer cells, tissues and tumors in sample is investigated through Nanomaterial Surface Energy Transfer (NSET) process from human cancer cells, tissues and tumors to the surface of nanoparticles, and Surface Enhanced Raman Scattering (SERS) process, as effective fa...

Demonstrated Spatial Irrelevance of Gray Fox at Contaminated Sites: Are Ecological Risk Assessments for Mammals Necessary?
Lawrence V Tannenbaum, David M Bullis, Nicholas R Deuel, L Mike Conner, Michael J Chamberlain and Karl V Miller
Article Type: Research Article | First Published: June 30, 2018
Ecological risk assessments (ERAs) for contaminated terrestrial sites regularly include mammals as receptors-of-concern whose home ranges dwarf the sites by tens of times. As a consequence, opportunities to sustain chemical exposures of concern are greatly limited. In having notably miniscule densities as well, wide-ranging mammals are poorly selected species to evaluate because true populations are effectively non-existent at sites. Collectively, the case can be made that wide-ranging mammals a...

Recent Advances in Mercury Detection; Towards Enabling a Sensitive and Rapid Point-of-Check Measurement
Nurfatini Busairi and Amir Syahir
Article Type: Research Article | First Published: April 09, 2018
Heavy metals emission, in particular, mercury is ever increasing due to global urbanization and industrialization. Due to increasing number of health problems related to heavy metals contamination, monitoring it becomes a crucial task for authorities and environmentalists. Therefore, the development of a nanobiosensing technique that can detect mercury ions as low as 1 ppb for its limit of quantification is necessary to provide sufficient information to ensure a sustainable and healthy environme...

Assessment of Environmental Contamination by Wastewater from a Cocoa Processing Industry Using Genetic and Reproductive Biomarkers
Alabi A Okunola, Esan E Babatunde, Olorunfunmi J Temitope and Oludare O Evelyn
Article Type: Research Article | First Published: September 25, 2017
Food industries are among the major contributors to industrial wastes. Their wastewaters can pose a threat if untreated and indiscriminately disposed into the environment. In this study, we investigated the potential genetic and reproductive toxicity of Cocoa processing industry wastewater, by using the mouse Micronucleus (MN) and sperm morphology assays....

Accuracy of Admission Glasgow Coma Scale to Predict Aspiration Pneumonia in Poisoned Patients
Sebastien Champion and Vincent Spagnoli
Article Type: Short Commentary | First Published: August 01, 2017
Glasgow Coma Scale (GCS) assesses the need and guides tracheal intubation in trauma patients. GCS provides a practical method for assessment of impairment of conscious level in response to defined stimuli. GCS is the sum of 3 sub-scores for eye opening (1 to 4), verbal (1 to 5), and best motor (1 to 6) response to stimulations....

Long-Term Effects on Renal Function in Children and Adolescents Due to Environmental Exposure to Lead-Results from an 11-Year Prospective Cohort Study
Recio-Vega R, Gurrola-Mendez A, Valdez-Abrego C and Rivera-Guillen Mario
Article Type: Research Article | First Published: December 31, 2015
Lead is a widespread toxicant with well-established detrimental health effects. Environmental exposure to lead occurs through different means such as industrial and combustion sources, lead paint, folk remedies, glazed pottery, and sometimes by drinking water. Some groups are disproportionately exposed to lead, including those who live close to industrial facilities or with low socio economic status and workers in small or mobile workplaces such as radiator repair shops and construction sites......

Hydroxypyrene Excretion as Indicator of Cancer Risk in Street Sweepers and Polycyclic Aromatic Hydrocarbons (Pahs) Exposure
Mazzotta M, Mazzotta AD, d'Ettorre G, Cazzato RG, Simone C and Fernandez M
Article Type: Research Article | First Published: December 16, 2015
Exposure to polycyclic aromatic hydrocarbons (PAHs) is associated with possible carcinogenicity, according to European directives. Studies helped to clarify the contributions to the total dose resulting from environmental and occupational exposure, by tobacco smoke, by diet and skin absorption. Recently, it was shown that levels of 1-Hydroxypyrene U (1-OHPu) may be predictive of individual dose, environmental and employment exposure, proportionately even though indirectly expressing the concentr...

Article Type: Original Article | First Published: August 26, 2015
Even though the adverse effects on environment and organism health have been long and thoroughly studied, the problem represented by the continuous use of neurotoxic pesticides, in particular organophosphates (OPs, organic salts of the pyro phosphoric acid), is still open. These are considered as emerging pollutants, as their massive employment is relatively recent, dating after the ban of persistent organic pesticides. OPs are not persistent for a long time, as their half-life varies according ...
